KappaPride is a variant of one of the original emotes created for the streaming website Twitch.tv, called Kappa.
The emote was taken from a photograph that features Josh DeSeno, an employee of Justin.TV (now known as Twitch.tv) that was cropped and painted with rainbow colours to represent the LGBTQ community, unlike Kappa, which is in black and white.
The emote can be used to ask someone about them being homosexual/part of the LGBTQ community on Twitch.tv.
Based on a picture taken of Justin.TV employee (now known as Twitch.tv) Josh DeSeno, it was one of the original Twitch.tv emotes, uploaded in late 2015, 4 years after its original version Kappa has made it to the site and dominated the chat rooms.
Since its a variant of the most popular, original Twitch.tv emote and covering such a controversial topic, it has been heavily used since its upload in 2015.
As of 10/12/2019 according to the website StreamElements, 4Head is the 20th on the list of most popular/used emotes on the website Twitch.tv, making it one of the more popular emotes.
